The Travis Linux distribution must be upgraded because the Trusty
(Ubuntu 14.04) image does not have Python 3.9. Xenial (Ubuntu 16.04) is
the earliest version that offers Python 3.9.
I have not chosen a later release, in order to aid restoration of Python
2.4 - 2.6 tests.
I hope this will prevent AWS Elastic Container Registry returning 429:
Too Many Requests error, due to the burst of activity from multiple VMs,
when a CI build begins.
The ansible_mitogen test suite takes over an hour when Ansible is not
accelerated by Mitogen. This change aims to reduce that by skipping
tests with a large number of iterations when the linear strategy is
chosen.
The tagged tests are intended to uncover Mitogen resource leaks. Since
Mitogen is not invoked when strategy=linear, the slight reduction in
test coverage is an acceptable trade off.
These are not part of the official testing regime (tests run for pull
requests). I find them convenient for local development.
Limitations
- Python 2.7+ only. No Python 2.4, 2.5, or 2.6.
- Requires Pythons pre-installed (e.g. DeadSnakes, pyenv)
- No coverage of alternate controller OS (e.g. MacOS)
The environments tested by default are
py27-mode_ansible-ansible2.10
py36-mode_ansible-ansible2.10
py39-mode_ansible-ansible2.10
py27-mode_mitogen
py36-mode_mitogen
py39-mode_mitogen
py27-mode_mitogen-distro_centos7
py36-mode_mitogen-distro_centos7
py39-mode_mitogen-distro_centos7
CALLBACK_VERSION et al are documented as required in
https://docs.ansible.com/ansible/2.10/dev_guide/developing_plugins.html#callback-plugins.
The need for document_fragment is noted in
cfa8075537/lib/ansible/plugins/callback/default.py (L28-L32)Fixes#758
This addresses the following error, seen while running
`ansible_tests.py`.
